Summary
The Hedgehog signaling pathway
Area of Science:
- Developmental biology
- Cell biology
- Molecular signaling
Background:
- Neural crest cells (NCCs) are crucial for development.
- Wnt, FGF, and BMP pathways are known regulators of NCCs.
- The Hedgehog (HH) signaling pathway's role in NCCs is understudied.
Purpose of the Study:
- To investigate the role of the transcription factor GLI3 in neural crest cell development.
- To elucidate the specific functions of the HH pathway in NCCs.
Main Methods:
- Co-expression analysis of GLI3 with NCC markers in chick, mouse, and human embryonic stem cell-derived NCCs.
- Early knockdown of GLI3 to assess effects on NCC specification markers.
- Conditional knockout of Gli3 post-specification to evaluate cranial NCC differentiation.
Main Results:
- GLI3 and HH pathway members are co-expressed with NCC specification markers.
- Early GLI3 knockdown reduced key NCC specification markers.
- Gli3 knockout post-specification impaired cranial NCC differentiation into ectomesenchymal derivatives.
Conclusions:
- GLI3 plays dual temporal roles in NCC development.
- GLI3 is essential for early NCC specification.
- GLI3 is critical for later cranial NCC differentiation.

Determination
20.6K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

Neurulation
45.0K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.4K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Hedgehog Signaling Pathway
9.7K
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

Gastrulation
65.6K
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Notch Signaling Pathway
6.3K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...
